How To Monitor Your CPU Temperature

I recently bought my nephew’s desktop computer with the following specs:

  • Intel(R) Core(TM) i5-2300 CPU @ 2.80GHz
  • Mainboard Model: ASUS P8H67-M PRO
  • BIOS: American Megatrends Inc. version 1104
  • AMD Radeon HD 7800 Series
  • Microsoft Windows 10 Home 64-bit (Build 17134)

A couple days ago I turned it on and it gave a CPU fan error. Ever since, I’ve been using SpeedFan to monitor the temperatures. My CPU temperature is constantly up in the 88-90C (198.4F – 194 F) range even when I’m not doing anything. And the CPU Fan speed is listed at 645 RPM.


According to SpeedFan I don’t have any other fans running, but there are two case fans running all the time: one on the back, and one on top.

Here are all the temperatures listed by SpeedFan at the time of this writing:



So online I went to see what would be the best course of action. It seemed that I might need to replace the CPU fan, but I decided to to try a different program called Speccy.

A second opinion wouldn’t hurt. When I ran this one, the temperature was a lot lower at only 35C (95 F).



Online forums suggested another program called HWiNFO and it confirmed the temperature of my CPU at around the 37C (98.6 F) mark, so I think SpeedFan is giving me faulty information.


I’m relaxing a little bit more now and I’m convinced my computer isn’t going into a complete meltdown.


So, my recommendations are:
